The use of environmentally friendly finishing materials allows us to create a space where we can feel nature and to have stability and peace in the city center. In this paper, we examined the sensitivity of people to the three café spaces where wooden finishing materials are used in the space elements that change according to people's demands for environmentally friendly space due to pollution of living environment. First, we examined the wood and finishing materials and emotional vocabulary through literature review and previous research. Second, the values of L ^*, a ^*, b^* and sR, sG and sB values were extracted by using a line spectrophotometer (Ci6X). Third, we conducted a 7 - point scale questionnaire based on the extracted 13 pairs of emotional vocabulary. Using SPSS 21, frequency analysis by descriptive statistics, crossover analysis by visiting purpose and intention, and emotional lexical factor analysis were performed. Through the study, the following points were found. First, CB (The Coffee Bean), SB (Starbucks) and HS (Hollys Coffee) showed differences in CB (65%), SB (40%) and HS (37%) in the spatial analysis. Second, CB gave color similar to the color of wall and furniture wood, but HS changed the color or brightness of wood finishing color of furniture. HS or SB showed favorable use of wood color scheme. Third, SB (26.3%) and HS (19.7%) were selected by taste. Fourth, there were differences in the items of CB, 'local-exotic' and SB 'dark-bright' in the factor value. The use of wood finishing materials differed in the atmosphere evaluation depending on the spatial factors and the color of the furniture. However, in this study, there are many factors that are insufficient in the accuracy of the ratio of the applied wood finishing material to the space element and the amount of the survey. If we further study the evaluation of emotional image according to the ratio of wood finishing materials, we think that it is necessary to study now that interest in environmentally friendly is increasing.

With people's awareness of environment-friendly buildings recently increasing, there is a need to develop environment-friendly construction materials to reduce indoorair pollution levels. Thus, efforts to develop loess finishing materials that can replace the finishing materials currently being used (e.g., gypsum boards and chemical products) are underway. An analysis of the characteristics of domestic loess products,however, revealed that the cracks on loess products can be lessened and their strength can be improved by adding chemical ingredients to them. Thus, this research sought to use 100% natural materials and to develop loess finishing materials. In the experiments that were conducted in this study, appropriate mixture ratios of loess and sand/silica sand were found, and cracks and contraction ratio changes in samples were analyzed by differentiating the ratios of natural ingredients, such as lime, fine jute threads, gypsum, and jute cuttings. Loess'particle size distribution was found to have a high correlation with loess decoration, and it was discovered that the mixture of lime and fine chute threads could improve the contraction ratio. Through this study, which made use of natural ingredients, environment-friendly construction materials that can exercise the original function of loess were developed.

In this study, improving the wash and rubbing fastness of a natural coloring matter from Madder extract dyed on Tencel nonwoven. The cationic finishing agent(RBP), nonionic finishing agent(HPX) and mordant(PAW) were used to improving the color fastness. The two types(exhaustion and pad-dry-cure) finishing process were investigated with various finishing agent concentration. The color strength, wash and rubbing fastness of Tencel nonwoven dyed with Madder extract have been evaluated by various dye concentration and finishing agent. The exhaustion process treated with the cationic finishing agent(RBP) was effective to improving washing and rubbing fastness.

In order to establish the standard manufacturing condition of PET flame retardant sheets, physicochetnical properties of the samples made by the conventional flame-retardant finishing were systematically investigated, including compatibility among flame retardant agent and finishing auxiliaries, surface property, and wicking property. From this results, the addition of washing and renapping process after the shearing process was required for the more effective in producing PET flame-retardant sheet by the standard finishing. The effect of the modification of the regular flame retardant finishing process was studied by FTIR, TGA, and flame retardancy test.

Recently, as the problems according to lack of skilled labour and superior construction materials were gathering strength, there were required the advent of a special materials in building construction division. As a view of the point, the cement-based Self leveling mortar was developed for improvements of the former problems. The Self leveling mortar has the all kinds of the properties as followed the premixed products in plant, self-smoofhing, non shrinkgae etc, accordingly the finishing of concrete floor don't need skilled labour. The purpose of this study is to establish the introduction of a finishing construction method for concrete floor and slab using the cement-based self leveling mortar. Presented is a study on the basic properties of fresh and hardened self leveling mortar. To this end, an actual floor's finishing construction using the cement-based self leveling mortar was conducted in approximately 1,800㎡ floor as to compare the flatness and levelness after finighing.

An operation planning of lift car is crucial in tall building construction especially it's arrangement plans, because it is related with transportation distance of finishing materials affecting construction productivity. Since tall building construction, composed of complicating and huge plane have complex traffic lines of finishing materials, to determine the position of lift car empirically or intuitively has limits. Therefore this paper suggest an optimum layout model of lift car minimizing the transportation distance both at site-level and floor-level using Graph theory and Dijkstra algorithm.

This study conducted on the introduction of recycled cellulose fibers, which are widely used in the textile industry as eco-friendly biomass materials, into polypropylene resins, which are mainly used for interior and exterior materials such as door trims and console parts of automobiles. In general, cellulose fibers can affect mechanical properties and have a lightening effect when used as a reinforcing agent. However, since cellulose fibers have hydrophilic properties and have relatively low compatibility with industrial polymer resins, they are used in combination through fiber hydrophobic surface treatment. Therefore, through this study, the reforming reaction conditions optimized in terms of hydrophobicity and workability for cellulose fibers are studied. Furthermore, polypropylene containing surface-modified cellulose fibers was prepared to compare physical properties by fiber content and study optimized content.

건축물에서 사용되는 에너지를 줄이기 위하여 다양한 연구 및 정책이 진행되고 있으나 건축물에서 구조재 및 실내 외 마감재로 폭넓게 사용되는 목재의 열적 특성에 관한 연구는 미미한 실정이다. 이에 따라, 본 연구는 목질재료와 비 목질재료의 전열성능을 분석하기 위하여 목질재료가 주로 이용되는 주거용 건축물을 대상으로 열성능이 취약한(열교 발생) 부위를 선정하고, 각 부위별로 구조재와 마감재의 구성에 따라 총 16 Case에 대해 전열성능 분석을 실시하였다. 전열 해석 시뮬레이션 도구는 ISO 10211의 계산 방법을 따르는 Physibel Trisco를 이용하였다. 해석 부위의 모델링 역시 ISO 10211에서 제시된 기준에 의해 실시하였으며, 경계 온도 조건은 에너지절약설계기준에 따라 실내온도 $20^{\circ}C$, 실외온도 $-11.3^{\circ}C$(서울 기준)로 설정하였다. 구조는 콘크리트구조와 비 목질재료마감, 콘크리트구조와 목질재료마감 그리고 목구조에 목질재료마감의 경우에 따라 구분하였다. 부위는 벽체, 지붕, 층간바닥 및 최하층 바닥 등으로 구분하여 시뮬레이션을 진행하였다. 결과로서, 콘크리트구조의 경우 형상적 원인에 의해, 목구조의 경우 형상적인 원인에 재료적 원인이 더해져 다발적으로 열교가 발생함을 확인할 수 있었다. 추가적으로 콘크리트구조에서는 단열재의 불연속 부위에서 구조적인 열교가 발생하고 목구조에서는 구조적인 열교와 이질재료의 적용 부위에서 재료적 원인에 의한 열교가 발생하는 것을 확인할 수 있었다. 또한 콘크리트 구조에 목질 실내마감재를 적용하였을 경우에는 벽체의 선형 열관류율 값이 감소하는 것을 확인할 수 있었다.

There are a large number of deteriorate mechanisms on the reinforced concrete structure and it acts complexly. In case of carbonation, it effected by environmental condition as well as properties of concrete. Most of all, water cement ratio and finishing materials have a great effect on the carbonation velocity. So, it is then aim of this study to suggest elementary data for the prediction of remaining life and the durability design by studying the relationship between carbonation velocity and permeability according to the waste cement ratio and kinds of finishing materials
